    Tiwbiau Mecanyddol wedi'u Troi'n Garw—Ni ddylai amrywiad mewn diamedr allanol a thrwch wal fod yn fwy na'r goddefiant yn y Tabl. Mae'r tabl yn cwmpasu goddefiannau fel y'u cymhwysir i ddiamedr allanol a thrwch wal ac yn berthnasol i'r maint penodedig.
    Tiwbiau Mecanyddol Tir—Ni ddylai amrywiad mewn diamedr allanol fod yn fwy na'r goddefiannau yn y Tabl. Fel arfer cynhyrchir y cynnyrch hwn o diwb wedi'i weithio'n oer.

    Gofyniad Prawf

    1. Prawf Caledwch
    Pan fo angen terfynau caledwch, dylid ymgynghori â'r gwneuthurwr. Rhestrir caledwch nodweddiadol yn Nhabl. Pan nodir hynny, dylid cynnal y prawf caledwch ar 1% o'r tiwbiau.

    2. Profion Tensiwn
    Pan fo angen priodweddau tynnol, dylid ymgynghori â'r gwneuthurwr. Rhestrir priodweddau tynnol nodweddiadol ar gyfer rhai o'r graddau a'r amodau thermol mwyaf cyffredin yn y tabl.

    3. Profion Annistriol
    Mae gwahanol fathau o brofion uwchsonig neu electromagnetig nad ydynt yn ddinistriol ar gael. Rhaid i'r prawf i'w ddefnyddio a'r terfynau arolygu gael eu sefydlu trwy gytundeb rhwng y gwneuthurwr a'r prynwr.

    4. Prawf Fflachio
    Pan fo gofynion arbennig ar gyfer glendid dur, rhaid i'r dulliau profi a'r terfynau derbyn gael eu sefydlu trwy gytundeb rhwng y gwneuthurwr a'r prynwr.
